The AAV-7A1 is the current amphibious troop transport of the United States Marine Corps. It is used by USMC Assault Amphibian Battalions to land the surface assault elements of the landing force and their equipment in a single lift from assault shipping during amphibious operations to inland objectives and to conduct mechanized operations and related combat support in subsequent mechanized operations ashore. It is also operated by other forces.

The AAVR-7A1 (Recovery) vehicle does not have a turret. The R7 is considered the "wrecker", as it has a crane as well as most tools and equipment needed for field repairs. It is by far the heaviest of the three, and sits considerably lower in the water. The AAVR-7A1 has a crew of three, not including the repairmen.
